The correct answer is the decrease in Ralph’s performance as he just started taking the guitar lessons last week and the increase of Jimi’s performance as he has been playing guitar for almost twenty years. The correct answers are decrease and increase.
Answer: increase/decrease
Explanation: Social facilitation refers to the phenomenon whereby individuals tend to perform better at tasks when they are surrounded by other people.
Since Ralph is a newbie, his performance is more likely to decrease as he has not mastered playing in front of an audience. A veteran like Jimmie will have no problem playing in front of an audience as he is already used to playing in front of an audience.
